MVVM -在TreeView中选择项目，并使用绑定在ListView上显示其属性

// Model
public class Project
{
    public string Name { get; set; }
    public string[] Properties { get; set; }
}

// ViewModel
public class ProjectSelectionViewModel : INotifyPropertyChanged
{
    public ObservableCollection<Project> Projects { get; set; }
    private Project selectedProject;

    public Project SelectedProject
    {
        get { return selectedProject; }
        set
        {
            selectedProject = value;
            OnPropertyChanged(nameof(SelectedProject));
            // 选中的项目发生变化时，更新属性显示的ViewModel
            propertyDisplayViewModel.UpdateProperties(selectedProject?.Properties);
        }
    }

    // 其他必要的实现，如INotifyPropertyChanged接口的实现和事件处理等
}

public class PropertyDisplayViewModel : INotifyPropertyChanged
{
    public ObservableCollection<string> Properties { get; set; }

    public void UpdateProperties(string[] properties)
    {
        Properties.Clear();
        if (properties != null)
        {
            foreach (var property in properties)
            {
                Properties.Add(property);
            }
        }
        OnPropertyChanged(nameof(Properties));
    }

    // 其他必要的实现，如INotifyPropertyChanged接口的实现和事件处理等
}

// View
<TreeView ItemsSource="{Binding Projects}"
          SelectedItem="{Binding SelectedProject}">
    <!-- TreeView的样式和模板定义 -->
</TreeView>

<ListView ItemsSource="{Binding Properties}">
    <!-- ListView的样式和模板定义 -->
</ListView>
